Acquiescence, or the tendency to respond to descriptions of conceptually distinct personality attributes with agreement/affirmation (acceptance acquiescence) or disagreement/opposition (counter-acquiescence), has been widely recognized as a source of bias that can substantially alter interitem correlations within scales. Acquiescence is also known to operate differently among some groups of persons; it is, for example, more pronounced among individuals with less formal education. Consequently, the biasing effects of acquiescence are of particular concern when the dimensionality underlying the item set of a measure is examined with representative samples comprised of persons with varying levels of educational attainment and evaluated with correlation-based statistical methods such as factor analysis. In the present study, we extended our earlier research by investigating the biasing effect of acquiescence on personality factor structures derived from the full-scale version of the Big Five Inventory (BFI) when administered to a large sample (N = 1,427) selected to be representative of Germany's adult population. Consistent with previous findings based on a short-scale version of the BFI, factor analyses of the unadjusted BFI item set failed to replicate the expected Big Five-factor structure in the low/medium and high educational groups, with distortions in factor structure more pronounced in the former group. Once acquiescence was controlled in the item responses for both groups, however, the obtained factor structures were consistent with the Big Five framework. The implications of acquiescence on the evaluation of the factor structure of personality inventories and for the validity of personality assessments are discussed. © 2013 American Psychological Association.

Purpose - The purpose of this paper from the series "Monitoring the Media: Spotlight on Social Media Research" is to look into different approaches to study uses of social media platforms - from user statistics to motivations for using specific features within a platform. Design/methodology/approach - Based on a literature review some general findings on social media usage are summarized alongside with examples of user activities that are rarely studied. Findings - The paper concludes that social media research has neglected to question the use of more recent features in social media platforms, such as Twitter favorites or Facebook hashtags, as well as the more "destructive" activities in social networking such as unfollowing. Originality/value - The paper draws attention to some features of popular social media platforms which are currently understudied. It raises awareness for these specific gaps in social media research and could inspire future studies to close the gap. © Emerald Group Publishing Limited 2016. Source

Objectives: General Strain Theory (Agnew in Criminology 30:47–87, 1992) has received broad empirical support, but little is known about moderators of the strain-delinquency relationship. This study tests whether self-control attenuates the relationship between a certain type of delinquency—violence—and its most important precursor, considered a type of strain: interpersonal provocation. This study compares the conditioning effects of risk-affinity and self-control/impulsivity on the provocation-violence link, since recent work suggests differentiating between both characteristics. Methods: The provocation-violence link is examined (1) using a scenario design with randomly varied degrees of objective provocation and a measure of projected violence, and (2) with measures of self-reported past violence and subjective sensitivity to provocation. The analyses are based on a large sample of seventh-graders (n = 2635) from five cities in Western Germany, interviewed in 2013. Linear probability models regressing violence measures on personal traits, provocation measures, and their interactions are estimated. Results: Both self-control and risk-affinity moderate the relationship between subjective sensitivity to provocation and past violent behavior. Students with high self-control are able to control their anger and do not turn violent, even when they feel provoked easily. However, only risk-affinity significantly amplifies the effect of objective provocation on prospective violence when simultaneously controlling for the conditioning effect of self-control. Conclusions: Findings underscore that both self-control and risk-aversion are important coping resources. This study highlights the importance of using internally consistent and mechanism-congruent measures in the study of illicit coping processes and conditioning factors and discourages from using composite, potentially multidimensional measures. © 2015 The Author(s) Source

This study continues a long history of author cocitation analysis (and more recently, author bibliographic coupling analysis) of the intellectual structure of information science (IS) into the time period 2006 to 2010 (IS 2006-2010). We find that web technologies continue to drive developments, especially at the research front, although perhaps more indirectly than before. A broadening of perspectives is visible in IS 2006-2010, where network science becomes influential and where full-text analysis methods complement traditional computer science influences. Research in the areas of the h-index and mapping of science appears to have been highlights of IS 2006-2011. This study tests and confirms a forecast made previously by comparing knowledge-base and research-front findings for IS 2001-2005, which expected both the information retrieval (IR) systems and webometrics specialties to shrink in 2006 to 2010. A corresponding comparison of the knowledge base and research front of IS 2006-2010 suggests a continuing decline of the IR systems specialty in the near future, but also a considerable (re)growth of the webometrics area after a period of decline from 2001 to 2005 and 2006 to 2010, with the latter due perhaps in part to its contribution to an emerging web science. © 2014 ASIS&T.

Authors such as Dryzek, Gough and Meadowcroft have indicated that social-democratic welfare states could be in a better position to deal with development of the 'green' or 'eco' state, and the intersection of social and environmental policies, than conservative or liberal welfare regimes (synergy hypothesis). However, this hypothesis has as yet not been examined in comparative empirical research. Based on comparative empirical data from EUROSTAT, the World Bank, the OECD, the Global Footprint Network and the International Social Survey Programme, we are carrying out two research operations: First, by applying correspondence analysis, we contrast the macro-structural welfare and sustainability indicators of thirty countries and ask whether clusters largely follow the synergy hypothesis. Second, we raise the issue of whether differences in the institutional and organisational capabilities of combining welfare with environmental policies are reflected in people's attitudes and opinions. With regard to the first issue, our results suggest that there is no 'automatic' development of the ecostate based on already existing advanced welfare institutions. Representatives of all welfare regimes are spread across established, deadlocked, failing, emerging and endangered ecostates. As for the second issue, the results are mixed. While responses to the statements 'economic growth always harms the environment' and 'governments should pass laws to make ordinary people protect the environment, even if it interferes with people's rights to make their own decisions' did not vary according to welfare regimes, people from social-democratic countries expressed more often than average their willingness to accept cuts in their standard of living in order to protect the environment.
